Can we add more then one xml's in one xml for detecting more then one objects in a frame(Image)?
e.g: I want to detect nose and face at the same time. OpenCV contains face and nose in both files, but I want their combination to detect both at the same time.
Yes, you can do it. New OpenCV sample for face-detection comes with this property.Check it out.
See the result below. It has detected face and eyes in the same image.
